Transitions® everyday lenses get as dark as ordinary sunglasses. If you prefer the darkest lenses available we recommend Transitions® XTRActive®, our darkest everyday lenses ever.
Photochromic lenses react to their environment so the level of darkness is affected by extreme temperatures, UV exposure and lens materials.
Transitions® lenses darken immediately upon exposure to UV light. The level of darkness will depend on the amount of UV light present, time of day and direction of the sun.
